Hi Bhavesh, To enable SSO in SuccessFactors in provisioning you need goto the
Company then Edit Company Settings -> Single Sign-On (SSO) Settings and there you will find multiple sections the first two are
Single Sign On Features
Single Sign On Settings
The first one "Single Sign On Features" is to turn ON or OFF SSO - you do this at the end once your SSO setting are in place. The 2nd one "Single Sign On Settings" is where you will choose which type you want (depends on with which system you want to enable the SSO) and configure the parameters.
But before you do all that, SSO as you know means you will login to one system and will not require to login again to get into SuccessFactors. In this case please clarify what is that first system in your case, could be Windows based PC connected to company network, or can be an SAP portal System.
Thanks & Regards, Uppal
